A little problem with forward in a host with 2 addresses.

Miguel Da Silva - Centro de Matemática-3
Ladies and gentlemen, what follows a little fragment of the postfix log:

Jul 22 20:56:07 mordred postfix/smtp[29065]: CF1C713104F:
to=<[hidden email]>, orig_to=<[hidden email]>,
relay=mx3.hotmail.com[65.54.245.72]:25, delay=3.5,
delays=1.2/0.03/1.1/1.2, dsn=2.0.0, status=sent (250 mail from IP
164.73.82.254 soft failed sender ID check. Please ensure this IP is
authorized to send mail on behalf of [google.com])

This computer is the mail server and DNS server. The NIC has 2 addresses
(164.73.82.67 and 164.73.82.254) and the DNS is configured this way:

cibonato@peligro ~ $ nslookup smtp.cmat.edu.uy
Server: 200.40.220.245
Address: 200.40.220.245#53

Non-authoritative answer:
smtp.cmat.edu.uy canonical name = mordred.cmat.edu.uy.
Name: mordred.cmat.edu.uy
Address: 164.73.82.67

cibonato@peligro ~ $ nslookup ns.cmat.edu.uy
Server: 200.40.220.245
Address: 200.40.220.245#53

Non-authoritative answer:
Name: ns.cmat.edu.uy
Address: 164.73.82.254

So, my question is... is there anyway to change something so that
messages like this at the top appears as being sent by 164.73.82.67
(smtp.cmat.edu.uy) and not 164.73.82.254 (ns.cmat.edu.uy)?

Thank you and greetings!!!

If this does not solve your problem, reply with more information (at least
the output of postconf -n) as advised in the DEBUG_README.
